In nearly two years I've not managed to obtain any touch-up for the Corris colour or the grey colour of the diamond cut wheels, so if you find some please let me know where from. In the meantime I'd recommend you apply a good coating of wax polish on the affected area which will help to seal it from water ingress, which would get under and lift the surrounding clear-coat lacquer if left untreated. I keep my wheels well coated and so far, after two years, they are still looking really good (despite picking up a couple of inevitable tiny stone chip blemishes)

I managed to get a touch-up kit for Corris from the LR dealership across the road from the Jag one (who had nothing). Comes as a 2-part kit with a paint pen and a clear coat !

I also noticed a very small mark on my 20" Venoms when washing the car last weekend.....
